Urgent!! Errors during one EJB calling other EJB in OAS

Question

Hi, I got the following errors when I try to
use one Session EJB to call another Session EJB in OAS 4.0.8.1, the EJB is deployed to OAS from JDeveloper 3.0. The code I used to call other EJB is the same as the code in client side:
public String callAnotherEJB(String strXML)
throws RemoteException, CreateException {
String ejbUrl = "oas://scott:8889/Mapping3/Mapping3";
String result;
// Setup the environment
Hashtable environment = new Hashtable();
// Turn JNDI on to OAS
environment.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY, "oracle.oas.naming.jndi.RemoteInitCtxFactory");
// Lookup the URL
Mapping3Home homeInterface = null;
try {
Context ic = new InitialContext(environment);
homeInterface = (Mapping3Home)javax.rmi.PortableRemoteObject.narrow(ic.lookup(ejbUrl), Mapping3Home.class);;
result = remoteInterface.responseEJBCall(strXML);
return result;
catch (Exception e) {
e.printStackTrace();
return "error during invoking responseEJBCall: "+e.getMessage();
=====
The error is as follows:
Creating an initial context
CORBA: org.omg.CORBA.BAD_OPERATION: ; nested exception is:
org.omg.CORBA.BAD_OPERATION:
java.rmi.ServerException: CORBA: org.omg.CORBA.BAD_OPERATION: ; nested exception is:

Can anyone help me?
Thanks!1

Using arrays instead of vectors, the Oracle WSDL toolkit was able to generate stubs/serializers for all my objects. Thanks for the tip! :)
For future reference though, is there any way at all for the Oracle WSDL toolkit to auto-generate stubs/serializers for objects wrapped inside a Vector?
